BOLT-CASING.

Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed March 29, 1906. Serial No 308.633.

To all w/w'm it WI/CI/Z/ concern:

Be it known that I, JOHN S. RAPsoN, of Elkins Park, county ofMontgomery, and

State of Pennsylvania, have invented an Improvement in Bolt-Casings Madefrom Stamped Sheet Metal, of which the following is a specification.

My invention has reference to bolts; and it consists of certainimprovements, which are fully set forth in the following specificationand shown in the accompanying drawings, which form a part thereof.

The object of my invention is to provide an inexpensive construction ofbolt-casing made from stamped sheet metal.

My invention consists of the body part or case carrying the bolt whenmade of stamped sheet-steel or other suitable metal and comprising along flat base with ends turned upward and perforated, also having twosmaller perforated portions stamped from the base and bent upwardintermediate of the ends, combined with a slidable bolt extendingthrough the perforations of the four upwardly-extending parts and havingmeans arranged upon it between the intermediate perforated upturnedparts to limit the movement of the bolt and hold it to the baseplate.

My invention further consists in providing the base-plate with one ormore u wardturned flanges of less length than t e distance between theintermediate perforated parts, which acts to lock the means on the boltto prevent it moving out of its extreme posi tions.

My invention also comprehends details of construction, which, togetherwith the features above set forth, will be better understood byreference to the drawings, in which Figure 1 is a perspective view of abolt embodying my invention. Fig. 2 is a plan view of the same. Fig. 3is a cross-section of the same-on line 3 3, and Fig. 4 is a plan view ofthe base-plate before being bent into the shape it finally assumes.

The structure embodied in this invention comprises the bolt part and thekeeper. The body or base A of the bolt part is a flat steel platestamped into the shape shown in Fig. 4 and then having its parts B B C CD D bent upward at right angles to the plane of the base, as shown inFigs. 1, 2, and 3. The base is rectangular and of considerable lengthand has its ends B B perforated to reoeive the bolt E. Intermediate ofthese end parts B B are the two upwardly-turned perforated parts C C,which are of greatly less width than the base-plate A and also act asguides for the bolt E. The end parts B B are preferably the full widthof the base A, whereas the parts C C are very much narrower, so as toleave body metal upon each side of said parts.

The parts D D are two parallel flanged portions stamped up from thebase-plates A and are of less length than the distance between the partsC C, and, moreover, they are out of alinement with the apertures in thesaid parts C C, so that the bolt E will be arranged between them. Thebolt E is provided with a laterally-extending handle F, by which thebolt may be shifted, and its shank is adapted to be received between theends of the flanges D and the parts C, as shown, so as to lock the boltin its extreme positions. two of the flanges D the bolt may be used as aright or left handed bolt, as desired, and these flanges also act as ameans of stiffening the base-plate in the direction of its length. Thetwo sets of transverse parts B and C act to stiffen the base-platetransversely.

I represents screw-holes, which are placed in the base-plate near eachend and between the parts B and C. The bolt E, extending, as it does,through the four bearing parts B C C B, also adds great strength to thestamped-sheetmetal base part to hold it against bending.

The keeper G may be made in any suitable manner. In the form shown it ismade of a strip of sheet-steel bent upon itself to form a flange K andthen again bent upon itself to form the plate part II, in which theoblong hole J for the bolt E is formed. The ends of the plate may beriveted together at L, as shown. The arts H and K are provided withscrew-ho es to secure the keeper to the door-frame. If desired, theflange K may be omitted It is evident that where the bolt part is not tobe reversible one of the flanges D may be omitted. Likewise one of theend parts B may be omitted and the bolt E shortened; but I prefer tomake the parts as shown, whereby the structure is reversible.

While I prefer the construction shown, I do not confine myself to theminor details, as these may be modified without departing from thespirit of my invention.

Having now described my invention, what By employing I claim as new, anddesire to secure by Letters Patent, is v 1. A bot structure consistingof a body of stamped sheet metal having a base provided with twoperforated end parts and two intermediate perforated parts of less widththan the base-plate, combined with a slidable bolt extending through theperforated end parts and intermediate perforated. parts and providedwith means between the two intermediate perforated parts to limit themovement of the bolt.

2. A bolt structure consisting of a body of stamped sheet metal having abase provided with two perforated. end parts and two intermediatepreforated parts of less width than the base-plate and also having alongitudinal flange D of shorter length than the distance between theintermediate perforated parts, combined with a slidable bolt extendingthrough the perforated end parts and intermediate perforated parts andprovided with means between the two intermediate perforated parts tolimit the movement of the bolt and adapted to look over the ends of thelongitudinal flange D to lock the bolt in its extreme positions.

3. A bolt structure consisting of the base part A of sheet metal havinga perforated end part B, two perforated parts C C of less width than thewidth of the base and two longitudinal flanges D D of less length thanthe distance between the parts C G and separated a distance greater thanthe diameter of the bolt, all of said parts B, C, C and D D being bentupward from and integral with the base part, combined with the bolt Eextending through the parts B and C O and between the flanges D D andhaving a laterally-extending handle F adapted to lock between the endsof the flanges D and the respective parts 0 C, the said flanges D Denabling the bolt structure to be right or left handed.

4. A plate from which to form the body of the bolt structure consistingof a long plate having its ends provided with holes, two intermediateoppositely-directed U-shaped cuts to form parts 0 Cwhich are alsoprovided with holes, and two oppositely-directed U-shaped cuts to formlongitudinal parts D D the latter outs being intermediate of the parts CC and with their uncut sides at right angles to the uncut sides of thesaid parts C C.

5. A bolt structure having a keeper consisting of a strip of sheet metalbent upon itself to form a flange K and also bent upon itself to form aplate H at right angles to the flange and provided with a bolt-hole.

In testimony of which invention I hereunto set my hand.
